22-80-320 - Miller 20 Series CO2 Flowmeter Regulator, 10-80 SCFH, CGA 320

Miller 20 Series Industrial Flowmeter Regulator - 22-80-320

The Miller 22-80-320 is a premium industrial-grade flowmeter regulator designed for precise control of shielding gases in MIG and TIG welding applications. Part of the renowned Miller 20 Series, this unit is engineered to deliver consistent performance in heavy-duty environments. It features a CGA 320 inlet connection, specifically optimized for Carbon Dioxide (CO2) cylinders, while the multi-scale flow tube also provides readings for Argon and Helium, offering versatility for shops utilizing various gas mixtures (adapter required for non-CGA 320 cylinders).

At the core of this regulator is Miller's exclusive Sure Seat™ filtered seat technology. This innovation incorporates a high-pressure seat assembly that filters out debris and contamination before it enters the seating area. This is particularly critical for CO2 applications, where contamination and freeze-up are common failure points. By preventing these issues, the Sure Seat extends the lifespan of the regulator and minimizes costly downtime associated with repairs.

Accuracy is paramount in shielding gas delivery, and the 22-80-320 excels with its unique self-centering ball guide. Unlike traditional flowmeters where the ball may float off-center and provide inaccurate readings (often leading to excessive gas usage), Miller's design keeps the ball centered within the tube. This ensures that the indicated flow rate is the actual flow rate, even if the cylinder or regulator is slightly tipped. The result is optimal weld quality without the waste of expensive shielding gas.

Durability is ensured through a rugged aluminum housing that encases the flow tube, protecting it from accidental impact in busy industrial settings. The flow tube itself is constructed from shatter-resistant polycarbonate resin and features a high-visibility green background, making it easy to read from a distance or in low-light conditions. Additional safety features include an auto-reset pressure-relief valve and an inlet stem filter. This unit provides a flow range of 10-80 SCFH and a preset outlet pressure of 80 PSIG.
